Could you provide your Fablo config JSON file? My first guess is that not all orgs are members of the channel.

It seems that's because of the issue: #466

Long story short since you have two organizations, the default endorsement policy is set to majority of orgs. In the invoke command you provide both peers: peer0.farmer.foodchain.com,peer0.distributor.foodchain.com, which totally makes sense. But is seems we have an issue with that kind of calls.

The quick solution is to probably set the endorsement policy for chaincode to require a single org to endorse:

"chaincodes": [{
  ...
  "endorsement": "OR('Farmers.member', 'Distributors.member')"
}]
